Description

Technical Field

[0001] The utility model relates to the technical field of bathing, in particular to a foam spraying device for bathing. Background Art

[0002] Showers are commonly used for bathing, but existing shower heads have limited functions and can only spray hot and cold water for washing. When using them for washing, manually applying shower gel to the entire body is tedious and prone to uneven application. Therefore, a foam spraying device for bathing is proposed to address the above problems. Utility Model Content

[0003] The utility model aims to solve the problem that current bath liquid needs to be applied separately, which is cumbersome and uneven, and provides a foam spraying device for bathing.

[0004] In order to achieve the above-mentioned purpose of the utility model, the utility model provides the following technical solutions:

[0005] A foam spraying device for bathing comprises a bath liquid box, an ejector, a three-way valve, a mixer and an air pump, wherein a water inlet pipe is connected to a first port of the three-way valve, a water outlet pipe is connected to a second port of the three-way valve, a mixer is connected between the water outlet pipe and the second port of the three-way valve, a first end of the ejector is connected to a third port of the three-way valve, and a switch is provided on the three-way valve for controlling water flow out of the second port or the third port; the second end of the ejector is connected to the bath liquid box, the third end of the ejector is connected to the mixer, and the air pump is connected to the mixer via an air outlet pipe.

[0006] This application adds a three-way valve. When the three-way valve is closed, water flows into the water inlet pipe, passes through the second port of the three-way valve, and flows directly out of the water outlet pipe. When the three-way valve is opened, the second port of the three-way valve is closed, and water flows into the ejector from the third port. Bath liquid enters the ejector from the bath liquid box, and then the water and bath liquid enter the mixer together. The mixer mixes the water and bath liquid, and the gas emitted by the air pump also enters the mixer to bubble the mixed liquid, so that foam flows out of the water outlet pipe, which has a better effect. The process of applying the bath liquid is also relatively simple. Just turn on the switch of the three-way valve, and after the air pump foams it, it is sprayed on the body, which is both uniform and simple.

[0007] Preferably, a controller is further included, the air pump is electrically connected to the controller, and the switch of the three-way valve can be manually controlled or electrically connected to the controller, so that after the switch of the three-way valve is turned on, the controller receives a signal and starts the air pump.

[0008] Preferably, a flow sensor is connected between the third port of the three-way valve and the first end of the ejector, and the flow sensor is electrically connected to the controller. When the three-way valve is in an open state, the controller monitors the flow sensor to determine whether water is flowing and thus knows how to control the air pump.

[0009] Preferably, the device further comprises a housing, wherein the ejector, three-way valve, mixer, and air pump are all located within the housing, wherein a mounting post is provided within the housing, and the three-way valve and controller are mounted on the mounting post. A body wash box is mounted within the housing and connected to the ejector, and a water inlet is provided on the outside of the body wash box for convenient addition of body wash.

[0010] Preferably, a power supply is also installed in the housing, and the power supply is used to provide power to the air pump.

[0011] Compared with existing technologies, this utility model has the following advantages: a three-way valve controls whether water flows out of the second or third outlet, an ejector preliminarily mixes water and body wash, a mixer thoroughly mixes them, and air from an air pump turns the mixture into foam before it flows out of the outlet pipe. This allows the shower device to spray both clean water and foam, making it both more convenient and simpler than existing hand-applying methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be described in detail below with reference to the accompanying drawings.

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] In the description of the present utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0018] like Figure 1 As shown, the present application provides a foam spraying device for bathing, comprising a bath liquid box 2, an ejector 3, a three-way valve 4, a mixer 5, an air pump 6, and a controller 10, wherein the ejector 3, the three-way valve 4, the mixer 5, and the air pump 6 are mounted in a housing 1, and the bath liquid box 2 is snap-fitted to the housing 1. A connecting post is provided on the housing 1, and a connecting hole of the air pump 6 corresponds to the connecting post.

[0019] The water inlet pipe 7 is connected to the first port of the three-way valve 4, the water outlet pipe 8 is connected to the second port of the three-way valve 4, and a mixer 5 is connected between the water outlet pipe 8 and the second port of the three-way valve 4. The first end of the ejector 3 is connected to the third port of the three-way valve 4, and a switch 9 is provided on the three-way valve 4 for controlling the water flow from the second port or the third port; the second end of the ejector 3 is connected to the shower liquid box 2, the third end of the ejector 3 is connected to the mixer 5, and the air pump 6 is connected to the mixer 5 through the air outlet pipe 11.

[0020] A flow control valve 12 is connected between the third port of the three-way valve 4 and the first end of the ejector 3. The flow control valve 12 is electrically connected to the controller 10. The air pump 6 and the three-way valve 4 are electrically connected to the controller 10. A power supply 13 is also installed in the housing 1 to provide power to the air pump 6. A one-way valve can be installed between the ejector 3 and the mixer 5 and on the air outlet pipe 11 to prevent reverse flow of water.

[0021] First, pour bath liquid into the bath liquid box 2. When the switch 9 in the three-way valve 4 is in the closed state, the second port is in the open state, and the third port is in the closed state. Water enters from the water inlet pipe 7, passes through the three-way valve 4 and the mixer 5, and then flows out through the outlet pipe 8. At this time, the flow sensor 12 cannot detect the flow rate, and the air pump 6 will not be powered on and will only function normally. When the switch 9 is opened, the second port of the three-way valve 4 is closed, and the third port is opened. The water in the three-way valve 4 does not flow out directly through the mixer 5, but enters the ejector 3 through the flow control valve 12. At the same time, the flow control valve 12 triggers the controller 10 and the air pump 6 to operate, and the bath liquid and water enter the mixer 5 through the ejector 3. The gas blown by the air pump 6 also enters the mixer 5 at this time. The mixer 5 fully dissolves the three, generating foam that flows out of the outlet pipe 8.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
